Originally posted by BrainTeased Hey guys if the OS TR 3 port is 1.1hp would anyone know what the OS TR-P(T) 5 port turbo engine max hp is? tried looking online but couldnt find any HP specs. And now im confused with this engine i once heard that this engine has no power in take off, yet lots of power in top end. Now reading this thread its the opposite you guys say it has lots of punch but not much top end... my track is small and technical so i desire a punch/good take off engine i know novarossi's are the best answer, but if i could save on a few bucks i'd like to get the OS TR-P(T) 5 port for its price and the reliability and long life factor!

if ur longest st8 is abt 35m-40m with a technical infield then the OS 5 port wuld be the best choice

Giving you a $400 Nova MAX or JP mod engine does not make your car faster..........

However, your track size.........does determine how fast and what engine you can go........

I saw some track has a 100 foot long straight but have 10 plus turns inside and out............and engine like OS -TR will definitely KICK some JP mod or Nova MAX engine behind.....

Don't forget, track racing is all about skill, tunning and setting....you don't win a race because your 0-60 in less then 2 second.......you need to know how to BRAKE after the straight then turn without fish tail....so, HP sometimes mean absolutely NOTHING...

I heard so many HORRIBLE story about OS-TR, don't get me wrong, I say HORRIBLE is because I heard so many NTC3 with TR (not even turbo) spank some serious behind over those Rody mod, JP and Nova Max motor.............again, engine that last 45 minutes main without overheating and still have consistant power (both low and high) WINS the race.

Of course, if you are racing with Factory driver days in and days out............then forget about the OS-TR.
